whenever I turn on my computer the time & date changed

Every time I turn on my computer the hour and the date has changed. It started a few months ago and I have tried everything I can think. How can I stop this problem!

There is a battery on the motherboard.  It is called / known as the "cmos battery".

Like all batteries, when it becomes weak then he cannot supply.   In this case, a low cmos battery / exhausted will not keep time.  Even when the computer is disconnected from the wall socket, the battery is designed to provide power and maintain the internal clock of the computers.

The cmos battery is like a watch battery and can be purchased where they sell watches.

Check the internet for instructions on changing the cmos battery.   With regard to the size / model battery, you can find it listed in your computer manual, online manual for your computer or battery iteself.
